CBJUDE-OIL BURNER.

Specification of Letters Patent.

Patented July 25, i916.

Application led August 3l, 19215. Serial No.' 48,205.

To all 'whom t may concern.'

Be it known that l', 'HERBERT C. 1WHIT- nui',`a citizen of the United States, residing at Redlands, in the county of San Bernardino-and State of California, have invented new and useful Improvements in Crude-0il Burners, of which the following is a speciication.

My invention relates to an oil burner and in particular to a burner using crude oil as fuel.

lt is an object of this invention to devise a. crude oil burner, which simple in construction and positive in operation. The fuel is sprayed into the combustion zone by means of a steam jet, and means are'provided for thoroughly atomizing the. fuel, whereby a colorless, smokeless llame and perfect combustion are produced.

"With these and other. objects in View, which will appear as the description pro ceeds, my invention consists in the construe tion and arrangement of parts hereinafter described and claimed.

ln the accompanying drawings which form a part of thig specification, I have illustrated a conrenient and practical ern-- bodiment of my invention, and in which,

Figure l, is a side elevation of the burner showing its arrangement in a furnace. Fie. Q, is afront elevation thereof. llig. 3, is a longitudinal cross section of the burner nozthe interior ofthe oil tube to the forward end of the nozzle ll, said oil duct being located in the lower part of said nozzle. A. larger outer tube li-3 surrounds theinncr oil tube l0 forming an annular chamber 16. A cap lll with central cylindrical bore of a size to lit the nozzle ll closes the outer end of the tube 13, the cap being externally threaded to engage the threaded outer cnfl of the tube 13. A l,land 15 closes the an nular chamber 16 at the inner end, and an L shaped coupling- 17 establishes communication between the inner tube l() and an oil supply pipe 18. 'A manually controlled needle valve 19 arranged on said coupling; controls the oil feed into the inner tube lll. As shown in Fig. l, the oil burner proiects into the combustion space of a. furnace 24 under a boiler 25. Spaced at a suitable distance from the end of the nozzle is a curved deiector plate 26 which serves to defleet and spread the flame issuing from the burner nozzle. A water pipe 27 .connected to any suitable Supply of water projects into.v

the combustion chamber on the under side of the burner to a point adjacent to the dellector plate then turns in a horizontal di rection at right angles therefrom to the other vertical side ofthe delector plate er.w

tending upwardly therefrom; then horizon tally again across said deiector plate; then horizontally above and to the rear of a burner and enters the outer tube 13 at a steam inlet 28. A. valve 29 located in said water pipe at a slight distance above Said inlet 9.8, controls the steam from said pipe -sinall channel 33, crescent shaped in cross section, is provided between the lower face of nozzle l1 and the lower interior face or cap 14C. This channel-:29 communicates with a vertical channel 30 formed between the cap 14 and the tube l() with the annular steam chamber' 16. As clearly shown in Fig. 3, cap lli is slightly longer than no?.- zle ll thlereby forming a small cylindrical recess 3l at the outer end of saidcap.

The operation of my improved oil burner is as follews: Crude oil is supplied through the pipe 'i3 into the horizontal tube l0. ln order to start the burner, it is necessary to l force the oil. through duct 12 which may lu;

effected in any suitable nia-nner. The issuing from the nozzle is ignited hy any' suitable means. Steam will be generated in the pipe 27 and supply the annular steam chamber 16 through the steam inlet port 23.

The Steam jacket serves to'heat the crude cil within the tube l0 to render the same more fluid, and may partly vaporize the same.

i The steam issuing through the duct 32 will inclined, and the Steam and oil jet issuing 11u from therefrom will intersect the horizontal steam jet issuing from the steam duct 33. The inter-Section of these two steam jets effects an intimate mixing and spreading of the fuel in the combustion chamber. The Water supply with which'pipe 27 is connected is under a s'ulicient head, so as to overcome the pressure of the steam generated in said pipe. It should be noted thatthe steam and Water pipe 27 is not located in the direct path of the flame but is disposed adjacent the outer edges of the defiector plate.

It will be understood that the steam may be supplied t0 the steam jacket 16 directly of steam. o

IVhile I. have shown the preferred form ofthe oil burnerknown to me, it is obvious that various changes may be made in the construction of the rburner by those skilled boiler 25 or'any other suitable source in the art without'departing from the spirit of my invention as covered by the appended claim.

I claim:

An oil burner comprising a horizontal oil feed tube, a valve controlled oil supply pipe communicating therewith, a steam jacket surrounding said feed tube, valve controlled inea-ns supplying steam to said jacket, a. burner nozzle provided with a reduced hori- 3 zontal oil duct communicating with said feed tube, a steam duct extending from the outlet of said oil duct at an angle to said steam jacket and a second steam duct lo-y cated below thej'outlet of/Said oil duct ,for 3 spreading and atomizing the fuel said steam ducts being inclined to each other.

In testimony whereof I have signed my name' to this specification. f
